42512725 ÷ 874 
Our goal is to divide 42512725 by 874.

Step 1:
The number 874 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 874

Step 2:
When dividing 42 by 874, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 874

Step 3:
874 goes into 425 0 times with a remainder of 425.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 425 leaves us with 425.
Fetch the next digit (1) from the dividend, attach it to 425 and continue: 4251 / 874

Moving on to step 4:
When dividing 4251 by 874, we get 4 with a remainder of 755.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3496 from 4251 leaves us with 755.
Fetch the next digit (2) from the dividend, attach it to 755 and continue: 7552 / 874

Going ahead to step 5:
When dividing 7552 by 874, we get 8 with a remainder of 560.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 6992 away from 7552, we end up with 560.
Append the next digit (7) from the dividend to 560 and continue with: 5607 / 874

On to step 6:
874 can be fit into 5607 6 times, resulting in a remainder of 363.
Write down 6 as next digit of the result. 
Result so far: 486.0
Subtract 5244 from 5607 to get 363.
Bring next digit (2) of the dividend behind the 363 and repeat the process: 3632 / 874

Let's proceed to step 7:
If we divide 3632 by 874, we get 4 and a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 4864.0
The remainder is 136 after subtracting 3496 from 3632.
Bring next digit (5) of the dividend behind the 136 and repeat the process: 1365 / 874

Advancing to step 8:
The number 874 fits into 1365 1 times, leaving a remainder of 491.
Use 1 as the next digit of our solution. 
Result so far: 48641.0
If we subtract 874 from 1365, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Let's proceed to step 9:
874 goes into 4910 5 times with a remainder of 540.
Use 5 as the next digit of our solution. 
Result so far: 48641.5
The remainder is 540 after subtracting 4370 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 10:
874 can be fit into 5400 6 times, resulting in a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 48641.56
Deduct 5244 from 5400 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
874 goes into 1560 1 times with a remainder of 686.
Write down 1 as next digit of the result. 
Result so far: 48641.561
The remainder is 686 after subtracting 874 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 12:
If we divide 6860 by 874, we get 7 and a remainder of 742.
The number 7 becomes the next digit in our result. 
Result so far: 48641.5617
Subtract 6118 from 6860 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

On to step 13:
874 can be fit into 7420 8 times, resulting in a remainder of 428.
Put 8 as the next digit of the answer. 
Result so far: 48641.56178
The remainder is 428 after subtracting 6992 from 7420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 14:
The number 874 fits into 4280 4 times, leaving a remainder of 784.
Use 4 as the next digit of our solution. 
Result so far: 48641.561784
Subtracting 3496 from 4280 leaves us with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 15:
The number 874 fits into 7840 8 times, leaving a remainder of 848.
Put 8 as the next digit of the answer. 
Result so far: 48641.5617848
Subtract 6992 from 7840 to get 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Advancing to step 16:
874 goes into 8480 9 times with a remainder of 614.
The number 9 becomes the next digit in our result. 
Result so far: 48641.56178489
Subtracting 7866 from 8480 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

After the division, we end up with 48641.56178489 and a remainder of 6.14e-07.
